What Makes Prévost's Water Unique?
Local geology and source profile
Prévost's drinking water is managed by the Ville de Prévost, drawing from the Rivière du Nord — Prévost is a municipality in the MRC La Rivière-du-Nord in the Laurentides region, on the Rivière du Nord between Saint-Jérôme and Sainte-Adèle, part of the lower Laurentians resort and residential corridor north of Saint-Jérôme, a community of residential properties, summer cottages, and rural estates along the Rivière du Nord valley, in the popular Laurentians recreational corridor that transitions from the suburban Saint-Jérôme commuter belt to the full resort culture of the upper Pays d'en Haut. Water undergoes coagulation, sedimentation, filtration, UV disinfection, and chloramination, meeting all Guidelines for Canadian Drinking Water Quality (GCDWQ) requirements. Hardness measures 83.5 mg/L (4.9 gpg) — classified as moderately hard by Health Canada, in an intermediate range between the lower and upper Laurentides supply zones.
Prévost draws from the Rivière du Nord at an intermediate point between Saint-Jérôme and Sainte-Adèle — at 83.5 mg/L, Prévost sits between the lower Laurentides Rosemère reference (63.5 mg/L) and the upper Pays d'en Haut Sainte-Adèle (114 mg/L from batch 36), reflecting the gradual increase in Ordovician carbonate dissolution as the Rivière du Nord collects more minerals along its descending course from the upper Laurentian Shield to the lower valley. Water quality reports are published under Ministère de l'Environnement oversight.
At 83.5 mg/L, Prévost homes experience light to moderate scale deposits — cleaning every two months is adequate. Health Canada lead precautionary guidance applies to pre-1975 properties in the established Prévost Rivière du Nord corridor residential area.
Geology & Source: Supplied by the Ville de Prévost from the Rivière du Nord in the lower Laurentides corridor — the Prévost supply from the Rivière du Nord south of Sainte-Adèle produces moderately hard water at 83.5 mg/L (4.9 gpg), between the standard lower Laurentides range and the harder upper Pays d'en Haut corridor.
